Easton EA90 SL Front
Details
We’ve upgraded our venerable EA90 SL wheels, dropping weight and increasing strength. Now, for the first time, Easton is making a tubeless ready wheelset. This allows for durable Sapim straight-pull spokes with standard nipples, enhancing durability and reducing the need for proprietary parts. A completely redesigned rim features a category-leading 19.5mm internal rim in a deeper and stiffer 27mm blunt shaped rim that borrows from our aerodynamic Fantom shape. Finally, these battle-tested wheels are centered on our award-winning Echo hubs. This wheelset is completely hand-built and acoustically tuned using Easton’s painstaking wheel building methods.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
